, AY a subject of the King of Great Britain and Ireland; residing 'at. 5 Upland road,"E ast Dulwich, London,v England, has invented Connected with ShipsZ-Boat Handling and Launching Apparatus, ofwhich the followi is a specification, U

supporting boats on the boat and moving them across the deck when required to davits on either side of the ship and has'for its object to provide apparatus of simple construction that shall be easy of control" and capable of operating under the most adverse conditions, as for example, when the ship has considerable list.

According to this invention the boats are supported in rows one or more in height by means of chocks on pairs of flanged rails laid athwa-rt the boat deck, the chocks being mounted to run on the rails and actuated by chainsconnected by ropes with winches arranged to actuate the chains or other means to move the chocks in either direction on the rails. Means are also provided for holding the boats down in the chocks, consist ing of traveling posts or uprights with hooklike yokes at their upper ends arranged to engage over the gunwales of the boats and.

supporting and guide wheels at their lower ends which engage over and under the top flanges of the rails. Falls are also led from barrels on the winches over the davits and also ropes for swinging the davits outboard or inboard, the winches employed being preferably of the type described in our prior specification No. 8590/14 with suitable auxiliary barrels mounted in the frames and geared with the actuating worm shaft.

The invention is hereinafter described. with reference to the accompanying drawings in which:

Figures 1 and 2 illustrate conventionally in plan and elevation, boat handling apparatus constructed according to this invention.

Fig. 3 is an elevation of one of the davits suitable for use with the boat handling means shown in Figs. 1 and 2.

On the rails, chocks c are mounted to run on pairsbf wheeled, 'saidchocks comprising side plates or checks 0 depending on opposite sides of the rail flange and carrying suitable seatings 0 for the boat keels. The wheels d are mounted inside the chocks on hearing axles e, suflicient space being left between each pair of wheels for the accommodation of a chain 7 or other means which is attached to a transverse distance bolt 9 secured between the side checks. The chocks are all coupled in like manner with the chain 7 which slides on the top of the rail a and passes over pulleys k at the ends of the rail-Figs. 1 and 2its opposite ends being connected to ropes i which are led under each rail in opposite directions, and over suitable pulleys 7' j to a winch barrel is, the chains of each pair of rails with their connected ropes forming one continuous flexible operating cable which when wound in either direction by an ap- As the chocks a with the boats w supported thereon reach in turn the launching position, the boats are lifted out of the chocks by the davits and as the loaded chocks are successively brought into the launching position, the empty chocks in front of them are carried by the chain f over the ends of the rails a and supported in an inverted position underside the rails as shown in dotted lines in Fig. 2.

The boats 'w are maintained in position in the chocks by uprights or bars Z having wheels m at their lower ends arranged to run above and below the flange of the rail, and yokes n at their upper ends adjustable in height and capable of engaging over the gunwales of the boats. These uprights are placed in position over the ends of the rails,

- the upper flanges being suitably cut away to enable the lower Wheels to be passed under the said flanges, and to set free the uprightswhen the boats are being run outboard.

The davits 0, Which are illustrated, areof the ordinary type, are swung outboardor inboard by ropes p Wound in opposite di-' rectionson drums or pulleys g on the davit osts and also on a Winch barrel '1', while the falls 8 are led over loose'pulleys 't mounted on the davit to rotate about the. same axis and over other suitable guide pulleys-u to the fall blocks 1).

It Will be seen that with the improved apparatus boats can be kept in the most convenient positions for launching by the davits and tackle from both sides of the ship, or quickly transferred from one side of the Ubpies as this patent may be obtained for uprights. embracing the rail flan es" one oftheir ends and engaging thefgunwales of the boat with their other end.
